Agenda

• Introductions• Project Overview• Ecosystem Service Framework & Tools

Break• Baseline, Basin-wide Ecosystem Service Value

• Group Discussion• Break out Discussions• Priority Actions and Next Steps

Project Overview

• Baseline Ecosystem Services Assessment• Basin-wide and for Upper & Lower Dan and for Lower

Roanoke subbasins• What are stressors, issues, opportunities, that may

affect ecosystem service delivery• Evaluate effects of those factors• Develop the “ESValuator”, a QGIS plugin to make

ecosystem service valuation easier and more accessible.

Ecosystem Services Framework

Ecosystem Services are “the effects on human well-being of the flow of benefits from an ecosystem endpoint to a human endpoint at a given extent of space and time (Johnson, et al., 2010).”

Ecosystem Services Framework

Human-focused, but driven by ecological processes.

Biophysical quantities+

Human needs and desires=

Ecosystem Services

Core Ecosystem Processes (nutrient and water cycles, weathering, erosion, etc.)

Beneficial Ecosystem Processes(biomass production, formation of pleasant scenery, water purification, etc.)

Ecosystem Benefits(food, fresh water, raw materials, energy, physical health, psychological well-being, knowledge, etc.)

Stressorsmay affect

entire system

Concept Map

(Sample)

Core processes produce

beneficial processes.

Water Regulation:(Timing)

Stressors alter

processes.

Climate change will lengthen droughts

Water Flow less

dependable

Benefits derive from processes

AND appreciation.

Irrigation water reduced-> crops lost

Benefits can be

(but do not have to be) expressed in dollars.

Value of ag shipments, personal income in farming, farm employment all indicate

economic value at risk

Using benefits has bio-physical

feedbacks.

Irrigation also modifies the system (don’t forget about feedback loops)

Using benefits also has policy and

market feedbacks.

PES program by which farms, restaurants, and consumers support

forest restoration efforts.

Ecosystem Services Assessment

• To enumerate and, possibly, quantify key ecosystem service values and impacts

• To provide a basis for land use management that restores, conserves and sustains ecosystem processes and benefits

• To support market-based and other relationships that provide resources for adaptation actions

• Payments for ecosystem services• Marketing and other partnerships• Revenue / cost sharing• Education

The Sandbox

Follow the Benefits “Upstream” (and Back).

• What are some key economic sectors?

• What benefits are they connected to?

• What processes are important to the supply of those benefits?

• What is the condition of each key processes?

• How will climate change affect that condition?

• How will changes in the process’ conditions affect benefits?

Judgements are about Relative Change.

Baseline Estimates

• Land Cover (or Land Use)• Area in each land

• Ecosystem Service Productivity• $ per unit area per year• for a range of ecosystem services (water supply, recreation,

aesthetics, raw materials, etc.)• Minimum of “candidate values” or “comps” used today

• Area x $/area/year = $/year
